Recalls and investigations
2 recalls on the fuel and propulsion cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
Ford Motor Company (Ford) is recalling certain model year 2013-2015 Ford Taurus, Ford Flex, Lincoln MKS and Lincoln MKT vehicles equipped with 3.5L GTDI Ecoboost engines and 2013-2015 Ford Taurus Police Interceptor vehicles. A component within the fuel pump electric module (PEM) may overheat causing a loss of electrical power to the fuel pump.
Risk and remedy
Remedy: Ford will notify owners, and dealers will inspect the fuel PEM part number and replace the fuel PEM, as necessary, free of charge. The recall began on December 1, 2016. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S31.

Should you keep driving it?
This page can't tell you that. 0 of 35 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
